Abstract

The basic standard for the design of a seadefence structure in the Dutch coastal region is the stormsurge level with a frequency of exceedance of 10"* per year, the so-called basic design level. A new extensive and thorough statistical research for these levels was done on the datasets of five main tidal stations. Lot of attention was given to the preprocessing of the data in order to obtain indepen- dent and identically distributed data. Different extreme value models were applied, such as the Generalised Extreme Value Distribution and the Generalised Pareto Distribution. Also a modern distribution free extreme value model was considered. New frequency curves for all relevant tide gauge stations were derived, not only based on stati
